Resumen:
The optimum design of a non-dissipative LC snubber for step-up flyback converters operating in DCM (Discontinuous Conduction Mode) is presented. Experimental results prove that the optimization of the snubber plays a key role when high efficiency is required. A flat efficiency response larger than 91% along a wide operating range with a peak of 92.2%was accomplished with a transformer having a 6% leakage inductance.
